For the large family of ARMA models with variable coefficients we provide an explicit and computationally tractable solution representation, which yields the fundamental properties of such processes, including the Wold-Cramer decomposition and the covariance structure. These results are founded...

In this paper we investigate the behavior of inflation persistence in the United States. To model inflation we estimate an autoregressive GARCH-in-mean model with variable coefficients and we propose a new measure of second-order time varying persistence, which not only distinguishes between...

To develop forecasting procedures with a forward-looking dynamic general equilibrium model, we built a small New-Keynesian model and calibrated it to euro area data. It was essential in this context that we allowed for long-run growth in GDP. We brought additional asset price equations based on...

This study analyses the performance of real estate mutual funds for 1993 through 2001 period. The results indicate that real estate mutual funds do not provide positive abnormal performance on average. Fund performance to a large extent is determined by the performance of the real estate sector...

This paper studies the short run correlation of inflation and money growth. We study whether a model of learning can do better than a model of rational expectations, we focus our study on countries of high inflation. We take the money process as an exogenous variable, estimated from the data...

German Abstract: Dieser Beitrag möchte einen Impuls zur stärkeren Berücksichtigung von Genderaspekten in makroökonomischen Modellen geben. Am Beispiel der Philipps-Kurve geht es um die Frage, ob sich das Erwerbsverhalten von Frauen und Männern so stark voneinander unterscheidet, dass sich...

This paper introduces the concept of a Forecast Combination Equilibrium to model boundedly rational agents who combine a menu of different forecasts using insights from the forecasting literature to mimic the behavior of actual forecasters. The equilibrium concept is consistent with rational...

We offer a novel methodology for assessing the quality of inflation reports. In contrast to the existing literature, which mostly evaluates the formal quality of these reports, we evaluate their economic content by comparing inflation factors reported by the central banks with ex-post...

This collection of papers analyzes the versatility and predictive power of survey expectations data in asset pricing and macroeconomic forecasting. The first paper, Using Sentiment Surveys to Predict GDP Growth and Stock Returns sheds new light on the question of whether or not sentiment...

Japan is the most significant economy in the world today, because it exemplifies fifty years of declining economic growth for the major advanced economies. This paper provides an overview of distinct models for economic growth, inflation, interest rates, and the yield curve and applies them to...
